You definately can render out stereo
but both ansel and panocapture plugins are very slow for something like stereo 4k
the other way is to just take the vr output and plug that into your stereo tv.
How you would do that
IDK
but there probably is a way to send the vr stream to your display software
If I can see stereo in my HP Reverb, you should be able to capture that same stereo signal.
